They're probably just going to be tsundere as fuck to each other before Mako tells them to stop acting stupid.
Then again, it's hard to say what's going to happen next episode, maybe some mind control shenanigans will go on and we'll have to wait until ep 24 for actual interaction between them

It means something like "stop saying nonsense". I would translate it for: "Yeah, keep dreaming".
